Abstract: The horn housing may comprise an inner metal shell in the shape of a hexagonal box open at one end fitting into a similarly shaped outer dense solid box similarly open at one end. Space between the inner and the outer boxes being filled by a low density sound absorbing filler, and the inner box being connected to the outer box by vibration absorbing bolts. The outer box is mounted to a structure by vibration absorbing mounting brackets. When a high decibel horn or siren is mounted in the inner box to directed sound through the opening, most of the sound propagating sideways towards the structure is absorbed by the housing increasing the comfort level of passengers or crew inside the structure.

Abstract: A fuel injection pump for internal combustion engines having in-line cylinder bushes, in each of which a pump piston defining a pump work chamber is guided, the piston being rotatable by a governor rod for the sake of fuel supply quantity regulation. Mounted on the pump housing is an adjusting device, in which an adjusting piston is guided axially parallel with the governor rod; the adjusting piston has a radial pin, which protrudes through a slit in the wall of the adjusting device and pump housing into an oblong slot of the governor rod, thus limiting the adjusting motion of the rod in certain operating ranges. The position of the adjusting piston determines the maximum governing travel of the governor rod in the full-load direction upon engine starting. The adjusting piston is variable via an adjustable stop acting upon one face end thereof and is also variable as a function of temperature via a temperature-dependent spring element disposed on its circumference.

Abstract: A mounting apparatus for attaining a tolerance-insensitive connection of a conductor track foil with contact pins of an electrical component. The conductor track foil includes two insulating layers with an intervening conducting layer with lands in the upper layer for soldering the conductive layer to the contact pins of the electrical component. The conductor track foil is lowered, positionally correctly, onto the electrical component by use of a mounting device. The bottom insulating layer and the conducting layer of the soldering lands, which are free of an insulating layer on the top, are pierced by the contact pins extending at right angles to the conductor track foil. The conductor track foil is released by the mounting apparatus. A soldered connection is made between the lands and the contact pins. As a result, an electrically reliably gap free conducting connection is attainable even if the contact pins are eccentrically associated with the soldering lands.

Abstract: In previously known shock absorbers, a throttle cross section can be controlled with the aid of a control slide. Because flow forces can never be avoided entirely, the magnetic force must be controlled as a function of the flowing pressure fluid flow. In the cylinder proposed here, having a control slide, an additional force acting upon the control slide results, which is directed counter to these flow forces and can at least partially compensate for them. The proposed cylinder is intended in particular for use as a shock absorber for vehicles.

Abstract: In known fuel injection valves, a perforated disk having metering openings is disposed downstream of the valve seat. Adjusting the static fuel quantity injected during the steady opening state of the fuel injection valve is accomplished by means of the precise manufacture of the metering openings. Despite the high expense and effort of manufacture, an undesirably high deviation in the static fuel quantity of the various fuel injection valves occurs in mass production. The static fuel quantity is adjusted directly at the completely assembled fuel injection valve, so that the deviation of the static fuel quantity of the various fuel injection valves is minimized. To this end, the valve housing and the perforated disk are moved relative to one another, and as a result the various free flow cross sections of the metering openings are varied until the injected fuel quantity flow match the required fuel quantity flow. The method according to the invention is suitable for fuel injection valves of various types.

Abstract: A fuel injection pump for internal combustion engines having a cup-shaped pump housing and a pump head enclosing the housing. The pump head has a cylinder in which a pump piston, which is set into simultaneous reciprocating and rotary motion by a cam drive, in the course of which it simultaneously acts as a distributor, encloses a pump work chamber that is filled with fuel upon an intake stroke and communicates with one of a plurality of injection lines upon the supply stroke. The resultant reaction forces and moments are supported according to the invention via a roller race supported directly on the pump head, and as a result the induction of force to the pump housing can be avoided.

Abstract: A fuel injection pump for internal combustion engines, having a pump piston that is guided axially and rotationally movably in a cylinder bore of a cylinder liner and that with a face end defines a pump work chamber.

On a jacket face, this pump piston has known oblique grooves for the high-pressure pumping diversion process, and also a recess, which cooperates with an annular groove in the cylinder bore and with a control opening which discharges into a low-pressure chamber, and on its end face the piston has a cutout formed by two different, deep shoulders; the cutout is recessed within the annular groove continuously and cooperates with a first control opening that discharges into the low-pressure chamber.

Abstract: The present invention relates to an automatic sheet cutting apparatus which cuts off a sheet like a knit or a woven fabric into a predetermined shape and more particularly to a vacuum air leakage preventive device combined with an automatic sheet cutting apparatus so that a vacuum air can be prevented from leaking through a clearance between a bottom surface of one of those brush-mounting bases aligned in parallel with a pair of endless chains and a top surface of the main body of the automatic sheet cutting apparatus. The vacuum leakage preventive device includes a shielding member on a movable arm which is movable into place relative to the main body and the brush-mounting bases to prevent a break in a vacuum which pulls the material to be cut onto the main body relative to a cutter.

Abstract: A known fuel injection apparatus, in which fuel and foreign matter outside the fuel injection valve can not flow past the injection valves because a flow opening is disposed between fuel supply conduit and fuel outlet conduit and of which degassing of the fuel takes place before it enters the injection valve, any foreign matter entrained in the fuel will not give rise to malfunctions in a pressure regulation. The penetration of foreign matter into the pressure regulator is prevented by means of an appropriate choice of the dimensions of the flow opening, which is provided between a filter element of the fuel injection valve and the wall of a receiving bore. The fuel injection apparatus is employed in fuel injection systems for mixture compressing internal combustion engines with externally supplied ignition.
